General Introduction

The fixed bed reactor is a reactor filled with a solid catalyst or a solid reactant foe the realization heterogeneous reaction. Solid matter is usually granular granular particle size of about 2-15mm ,stacked into a certain height on the bed .the bed is stationary and the liquid reacts through the bed. The fluidized bed reactor is a reactor in which the solid particles are in a suspended state by means of a gas or a liquid through a solid layer and subjected to a gas-solid or liquid-solid reaction .Advantage,The advantages of a fixed bed reactor;1.Small back mix, the fluid can be effectively contacted with the catalyst,2,The catalyst has a small mechanical loss,3.Hydrogenation is safe, reliable and stable

4.Modular design, versatility easy to install.5.Achieve the temperature pressure, liquid level, flow and others automatic control.6,Automatic and manual dual module control combined easy to operate7.Reaction  conditions high and low limit alarm can be set.

advantages  of fluidized bed reactors;1.Continuous input and output of solid materials2.Easy to realize the continuous regeneration and circulation suitable for the high catalyst deactivation rate reaction process.3.The movement of the liquid and the particles makes the bed have good heat transfer performance the bed  temperature is uniform and easy to control particularly suitable for             strong exothermic reactions
